Specification of Letters Patent.

Application'filed June 5, 1911. Serial No. 631,427.

Patented Mar. 4, 1913.

To all whom it may eoncern:

Be it known that I, Hans HAUGNEs, a

citizen of the United States, residing at Garrison, in the county ofMcLean and State of NorthDakota, have invented a new and usefuFSpringDrill-Eye, of which the following is a specification. This inventionrelates to improvements-in what may be termed drill or tool cableattaching devices.

The invention has for its object to provide for relieving the device,including its actutoward circumstances or conditions.

A further object is to allow the tool. or

drill to have a resilient action in performing the boring or drillingoperation, especially in actuatin the drillor tool from, or with a steelca le. i

A still further object is to provide for securing an effectiveandsubstantial connection between the tool or drill and its actuatingcable and to insure the ,tool or drill receiving a turning action. forsuitably effecting the boring or drilling operation.

A still further :object is to carry out the aforesaid ends in a simple,expeditious and tails of the construction and. arrangement of" the partswithout departing from the spiriteffective manner.

The invention consists of certain instrumentalities and featuressubstantially as the claims. In the accompanying hereinafter fullydisclosed and defined in drawing illustrating the preferred embodimentof myinvention,

wherein it will'be understood that various changes may be made asrelates to the deof the invention: Figure 1 is an elevational view ofthe device. Fig. 2 is a like elevation viewing the device in a directionat right angles to the point of view of Fig. 1. Fig. 3 '1s a sectionalvelevation of the device. Figs. 4 and 5 are transverse sections thereofas produced upon the lines 44 and 55, of

Figs. 1 and 2, respectively, viewing in the direction of the arrows.

Referring to the figures by characters-of reference 1 designates a toolengaging member having one end portion broadened, as

' at 6, and provided with slightly concaved sides converging toward thefree end of the .member 1 so as thus to .cons't'itutea wedge.

Fitted upon the opposed concave faces of the wedge 6 are the thickenedlower'ends stantially uniform in width, as will be. apparent byreferring to Fig. 2,'and each having a flat inner face and a roundedouter face. Those .ends of the guide strips 2 remote from the thickenedends 13 are formed .with enlargements; 10. constituting abutmentsforatiering 9 which, as shown, is provided with "diametrically opposedsp'ac ing lugs 11 extending between the enlarge- 13 of guide strips2,these strips being subments 10. Another tie ring 8 is mounted on theguide strips 2 close to the thickened portions 13 and mounted on theguide members 2 is acoiled spring 7 the ends of which bear against therings 8 and 9 respectively.

A flat bar 3 is slidably mounted between the guide members 2 and betweenthe lugs -l1, this bar being provided at one end with an eye 1 or thelike while its other end is provided with oppositely extending ears 12projecting beyond the thickened portions 13 and under the tie ring 8.

In assembling the parts of the device, the

' guide strips 2 are placed opposite to each other with their flat facesin contact .Whereupon the thickened portions l3thereof can be insertedsuccessively through the ring 9, spring? and ring 8. Thisis obviouslypermissible in view of the fact thatthe combined thickness of theportions 13 is less than" the internal diameters of the rings 9 and 8and ofthe spring 7 The lugs 11 are.

inserted between the enlargements 10 so as to hold the strips 2 properlyspaced after which bar 3 is inserted longitudinally successively intoring 8, spring 7, and ring'9 so as to bring the wings or cars 12 againstthe ring 8. The laststep followed in assembling the partsis theinsertion of the wedge 6 between the thickened portions 13, this wedgebeing secured to said thickened po-r-' tionsby' transverse bolts 5. Thusit will be seen that-all of the parts are fixedly connected and cannotbecome accidentally displaced as the result of any jolting to wh ch thedevice may be subjected. Spring 7 acts as a cushion, permitting relativemovement of the guide strips 2 and the bar 3, itbeing obvious that whenthe strips 2 move downwardly relative to the bar 3, the ring 9 andenlargements 10 will move with the strips 2 and thus compress spring 7against the rmg ,8. The wedge-6 of course holds the lower portions ofthe side strips 2 properly spaced so that they will not bind to anobjectionableextent upon the bar 3. The upper ends of the side stripsare held against objectionable binding by the lugs 11.

-the rings, said spacing lugs projecting between the enlargements, aflat bar slidable between the guide strips and between the' lugs, therebeing oppositely extending ears upon the bar and bearing upwardlyagainst one of the tie rings, a tool engaging member, and a Wedge-likeanember carried thereby and extending between and secured to the guidestrips, said guide strips having thickened ortions which, when spacedapart by the wedging members, cooperate with the enlargements on theguide strips to hold the tie rings against withdrawal from the guidestrips.

2. A device of the class described including spaced tie rings, spacinglugs upon one of the rings, a coiled spring interposed be tween andbearing against the rings, guide strips each having an enlargement atone end and a thickened portion at its other end, said strips beingmovable in contact and insertible, while in contact, through the ringsand spring, a bar slidable between the strips, means on the bar forengaging one of the rings, the lugs on the other ring, constitutingmeans for holding the guide strips spaced at one end to preventthewithdrawal of said end from the tie rings, a tool engaging member, and aspacing member carried thereby and insertible between the thickenedport-ions of the guide strips to-hold said portions spaced apart toprevent their withdrawal from the rings, said wedging mem- .ber andthickened portions being secured together. v

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
